Finally some Dany's Mag swap progress, and fuel line routing questions?

My '82 B150 318 had a 3 nipple filter, was probably 5/16" but worth looking for.
I'm finding the 5/16 ones pretty easy, not so much the 3/8 ones so far...
Lots of good part numbers from Prof Fate, but so far no onne that actually has them in stock..
